WATER-WHEEL.

Specification of Letters Patent.

Patented April '7, 1908.

Application filed September 9, 1907. Serial No. 392,022.

To all whom it may concern:

Be it known that I, WILLIAM J. PEARSON, a citizen of the United States, residing at Winchester, in the county of Douglas and State of Oregon, have invented certain new and useful-Improvements in Water-Wheels;

' and I do declare the following to be a full,

clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in water wheels.

The object of the invention is to provide a water wheel by means of whichhigh s eed and power may be obtained from a low lead and a comparatively small amount of water, means being provided whereby the flow of water to the wheel may be regulated.

With this object in view, the invention consists of certain novel features of construction, combination and arrangement of parts as will be mo e fully described and particularly ointed out in the appended claims.

In t is accompanying drawings, Figure 1 is a vertical sectional view of a water wheel and easing constructed in accordance with the invention; Fig. 2 is a horizontal sectional view of the flume showing a top plan view of the wheel casing; Fig. 3 is a similar view, with the top of the casing removed; and Fig. 4 is a plan view of the casing with the wheel and cover removed. v

Referring more particularly to the drawings, 1 denotes the flame through which the water is run to the wheel, and in the lower end of which is suitably mounted thewheel casing, 2, said casing being substantially circular in form and provided at diametrically opposite points with outwardly proj ectin segmental extensions, 3, at one end of whic are arranged beveled, obliquely disposed water deflecting plates, 4. The casing, 2, is rovided with removable cover plate, 5, w ich is preferably secured thereto by means of laterally projecting stub bolts, 6, arranged on the sides of the casing and which project u wardly through apertures formed in t e cover plate, and on the upper ends of which are screwed clamping nuts, 7. In the cover late at diametrically opposite points are ormed substantially V-shaped water inlet passages, 8. The underside of the cover plate adjacent to the larger end of the pas-' sages, 8, is beveled or inclined to facilitate the passage of the water through said passages, 8, into the casing. The passages, 8, are ada ted to be opened and closed by means 0 ates, 9, which are referably in the form of eIliptically sha ed plates having in their opposite ends notc es, 10, which are adapted to engage the end bars of yokeshaped guide frames, 12. The upper bar of the guide frame, 12 is provided with a centrally disposed opening, 13, through which is adapted to extend a threaded regulating stem or rod, 14, the lower ends of which is secured to the gates, 9. On the threaded stems 14 are screwed hand wheels, 15, which are ada ted to be screwed up or down to raise or ower the gates and thereby open or close the water passages 8. In the bottom of the casing, adj acent-to each of the deflecting plates, 4, isformed a discharge passage, 16, said passages being arranged at diametrically opposite points.

In the center of the bottom plate of the casing is arranged a pivot pin, 17, having an upwardly projecting conic'ally-shaped point,

- which extends into the casing and on which is pivotally mounted a wheel," 18. The pin, 17 has a threaded engagement with a boss, 19, arranged on the underside of the bottom of the casing, and the lower end of said pin is provided with a suitable head, 20, whereby the same may be turned to project the point of the same in the casing to a greater or less extent, thus rovidin for the adjustment of the wheel. he whee 18, is in the form of a circular disk, at diametrically opposite points in which are formed recesses or notches, 21. The notches 21 have one of their side walls formed straight and in line with the center of the wheel, as shown at 22, while theo ppo Pivota ly or hingedgy' are beveled on-one side as shown at 26. The

wings, 25 are pivotally connected to the wheel midway between their ends, said pivotal connection being concentric to the curvedwalls, 23, of the notches, 21 thus permitting said wings to swing freely into and out of engagement with the notches.

In operation, one or both of the gates 9 are opened in the manner hereinbefore described,

' the threaded upper ends of said r0 s whereby thus permitting water from the flume to rush into the casing. Said water-will force the wings to an open position, thereby confining the water entering the casin between said wings and the deflecting p ates, and the pressure of the water thus entering the casing will force the wheel around until the open plates reach the discharge passages adjacent to the deflecting-plates, 4, at which time the water asses out of said discharge passages, while t e open wing engages the beveled side of the deflecting plates and is folded back u on the flat surfaces, 24, on the side of the W ieel, which permits said wings to ass the deflecting plates. Immediately a ter the folded wings thus pass the plates, 4, they receive the impact of a fresh supply of water passing through the inlet openings, which again opens said wings and acts u on the same to force the wheel around in tlie manner hereinbefore described. Any number of water inlet passages and cover plates or gates may be provided and the ca acity of the wheel thereby increased or (EIIllJllShGCl by opening one or more of the gates and admitting a greater or less volume of water into the casing. By providing a plurality of water inlet openings, the wheel may be adapted for use with a very small or large head of water. The construction and ar rangement of the parts of the wheel rovide for a'maximum amount of speed an power from a minimum of water.

The Wheel is provided with a centrally disposed, upwardly projecting shaft, 26, which extends through an opening formed in the cover of the casing, and is provided on its upper end with a bevel gear, 27, or other suitable power-transmitting device, whereby the motion of the wheel and the power developed thereby may be utilized.

Having thus fully described my invention, what I claim as new and desire to secure by Letters-Patent, is:

1. In a water wheel, the combination with a flume, of a casing arranged therein, said casing having water discharge passages formed in its lower side, a water wheel revolubly mounted in said casing, a removable cover arranged on the latter, said cover having formed therein water inlet passages, vertically ad'ustable gates adapted to open and close said passa es, guide frames arranged on said cover to old and guide said gates in their movement, threaded operating rods secured to said gates and held in operative position b said uide frames, interiorly threaded han whee s adapted to be en aged with carried by said wheel, said the latter are actuated to open and close said gates, substantially as described.

2. In a water wheel, the combination with a flume, of a wheel casing arranged therein, said casing havin inlet and discharge assages, beveled de ecting plates arranged in said. casing, and forming therein oppositely disposed water-receiving pockets, an ad'ustable pivot pin arranged in the center of the bottom of said casing, a water wheel pivotally mounted on the inner ends of said pin, win s pivotally mounted on said wheel, a centrall y disposed. power-transmitting shaft secured to the wheel and projecting upwardly through said casing, a power-transmitting gear on the upper end of said shaft, vertically olperating gates adapted to open and close t e inlet passages of said casing, threaded olperating rods connected to said gates, and t readed adjusting wheels on the up er ends of said flume, said wheels having a threaded engagement with said rods whereby the gates are opened and closed, substantially as de scribed.

3. In a water wheel, the combination with a flume, of a casing arranged therein, said casing having inlet and discharge passages, obliquely disposed deflecting plates arranged in said casing, a Water wheel revolubly mounted in the latter, said wheel having radially disposed recesses formed in its periphery, a series of radially disposed water-engagingwings wings having a pivotal connection midway between their ends with the outer sides of the wheel, whereby one of said wings is adapted to engage with the recess in the wheel when in an 0 en or operative position, a curved outer su ace formed. on one side of said wings, whereby when the latter are folded to an inoperative position, said curved outer surface will form a continuation of the ,outer surface of the wheel, vertically adjustable, horizontallydisposed closing plates adapted to open and close the inlet passages in the casing, guide frames to hold and guide said gates in their movement, threaded adjusting rods connected to the up er sides of the gates and adapted to extend to the upper end of said flume, and hand wheels screwed on said ad justing rods to open and close the gate, substantially as described.
